How to copy rules from a template, when the local NR set was copied from a set that doesn't exists anymore?

Desired Outcome Goal:To copy normalization rules from a template, when the local set was copied from a set that doesn't exists anymore.

Procedure:Open a case to support team and ask to copy the rules. Currently, it is not possible to copy rules from a template when there is no NR set to copy from (by using the option "Synchronize with template" in the NR editor page). This problem is being handled in PRM-23061. Meanwhile, as a workaround, Exlibris support can copy the rules from within the template to the local rule set.
